9. Service tips
Experiences from the previous engine
model, Raket 85, have taught us that a
Raket engine should normally not require
any comprehensive levels of service
during a racing season, since we believe
that a Raket 95 engine will be used no
more than 50 times per season. We do
not believe that it should be necessary to
change bearings, sealing rings and piston
rings several times during a season, such
as is required with more extreme kart
engines. It is of course up to every driver
and mechanic to make their own deci-
sions about what they think is necessary
or best.
The following simple service routines can
however be said to fall into the category
of normal maintenance work:
1. Lubricating the clutch parts.
We recommend that you lubricate the
bearing of the clutch drum. The clutch it
self shall be clean and not lubricated.
2. Silencer
As we mentioned previously, it is possible
to drill out the rivets at the back edge of
the silencer.
When you have done this you can remove
the end of the barrel and thus even the
damping material that is lying wrapped
around the barrel. Assuming that the
carburettor is setup normally and correctly
it should not be necessary to change the
damping material during a season. How-
ever we would recommend a change prior
to the start of each new season.
3. Servicing the carburettor
The only aspect of your Raket 95 engine
that requires regular service is the
carburettor. A diaphragm carburettor is a
quite amazing component that is capable
of operating in chainsaws, cutters and
other testing applications whilst working
problem-free for several years at a time.
As long as you are careful to only refuel
using well-filtered fuel, and always drive
with the inlet silencer attached, then you
should also be able to get through a sea-
son without needing to disassemble the
carburettor for cleaning and control. On
the other hand you must possess the abil-
ity to clean and setup your carburettor. To
that end there now follows a short tutorial
in carburettor service.
The carburettor is a Tillotson 319 A. If we
follow the passage of the petrol through
the carburettor we will be able to quickly
describe the carburettor’s function.
The carburettor has two caps, one made
